They're miracle fruit tablets. They're made of a powdered fruit originally from West Africa that makes sour and bitter foods taste sweet. Basically you suck on one of these tablets (or eat the real fruit if you have it) and let it coat your taste buds. Then you eat something sour and be amazed at how sweet it tastes. The package bills them as a dieting aid . . . http://en.wikipedia.org/wiki...
